Abstract
The invention discloses a bridge-type contact for a circuit breaker, comprising a plurality of groups of contact piece units and supports for connecting all the groups of contact piece units; each group of contact piece unit comprises two opposite contact pieces; and a plurality of groups of positioning boss units for fixing the contact pieces at intervals are arranged on the supports. According to the bridge-type contact for the circuit breaker, because positioning bosses are additionally arranged on the supports, certain gaps are maintained between the contact pieces, so that not only is the heat dissipation performance improved, but also the friction between the contact pieces is reduced, and the improvement of the flexibility and the conductivity of the contact pieces is facilitated.
Description
Technical field
The present invention relates to a kind of bridge type contact, relate in particular to a kind of circuit breaker and use the bridge type contact.
Background technology
At present, circuit breaker uses the contact blade side of bridge type contact to be burnishing surface, directly fits each other between each contact blade; Because directly fitting in the contact blade side, makes that the frictional force between the contact blade is big, influenced the flexibility of each contact blade; In the actual electrical connection procedure; The contact blade that plays effective electrical connection has seldom significantly reduced the effective contact area of contact in the actual electrical connection procedure, has influenced electric conductivity; And directly fit in the whole side of contact blade, also influenced the heat dispersion of contact blade greatly.
Summary of the invention
The objective of the invention is to provides a kind of circuit breaker to use the bridge type contact to the problems referred to above, directly fits the problem of poor electric conductivity, heat dispersion difference with the contact blade of bridge type contact to solve traditional circuit breaker.
The objective of the invention is to realize through following technical scheme:
A kind of circuit breaker is used the bridge type contact; Comprise many group contact blade unit and be used to connect the support of respectively organizing the contact blade unit; Every group of contact blade unit is made up of two relative contact blades, and said support is provided with the many groups positioning boss unit that is used for the fixed interval contact blade.
Further, said contact blade unit is 12 groups.
Further, said contact blade is processed by copper product.
Further, said positioning boss unit is 6 groups.
Further, said positioning boss unit is made up of the positioning boss that is symmetricly set in the support both sides.
Beneficial effect of the present invention does; Said circuit breaker, makes to maintain certain clearance between the contact blade through on support, setting up positioning boss with the bridge type contact, has not only improved heat dispersion; And reduced the frictional force between the contact blade, helped improving the flexibility and the electric conductivity of contact blade.
Description of drawings
Fig. 1 is the structural representation of circuit breaker of the present invention with the bridge type contact;
Fig. 2 is the front view of circuit breaker of the present invention with the bridge type contact;
Fig. 3 is the end view of circuit breaker of the present invention with the bridge type contact.
Among the figure:
1, contact blade; 2, support; 3, positioning boss.
Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through embodiment.
Please referring to figs. 1 through shown in 3, Fig. 1 is the structural representation of circuit breaker of the present invention with the bridge type contact; Fig. 2 is the front view of circuit breaker of the present invention with the bridge type contact; Fig. 3 is the end view of circuit breaker of the present invention with the bridge type contact; In present embodiment; A kind of circuit breaker is used the bridge type contact; Comprise 12 groups of contact blade unit and be used to connect the support 2 of said 12 groups of contact blade unit, every group of contact blade unit is made up of two relative contact blades 1, and said contact blade 1 is processed by copper product; Said support 2 is provided with 6 groups of positioning boss unit that are used for fixed interval contact blade 1, and said positioning boss unit is made up of the positioning boss 3 that is symmetricly set in support 2 both sides.
Though positioning boss shown in the drawings unit is 6 groups; But the invention is not restricted to this; The positioning boss unit can be arranged to 11 groups as required, makes to be provided with positioning boss 3 between the contact blade 1, thereby makes bridge type contact system radiating effect and conductivity better.Circuit breaker of the present invention with the bridge type contact through on support, setting up positioning boss; Make and maintain certain clearance between the contact blade; Not only improve heat dispersion, and reduced the frictional force between the contact blade, helped improving the flexibility and the electric conductivity of contact blade.
Above embodiment has just set forth basic principle of the present invention and characteristic; The present invention is not limited by the foregoing description; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various variations and change, and these variations and change all fall in the scope of the invention that requires protection.The present invention requires protection range to be defined by appending claims and equivalent thereof.
